Flash memory card reader with low thickness

Abstract

A connective device in a partition and screen system comprises at least and upright post, a plurality of retaining pins, a plurality of trunking parts longitudinal, and at least a partition. The upright post is cylindrical with a homogeneous cross section with longitudinal slide grooves circumferentially disposed through the entire length thereof. The retaining pins are selectively inserted into the slide grooves and each of the retaining pins has an arched side with two opposite lateral edges. The trunking parts are connected to the respective coupling pieces so as to be positioned next to the upper end and the lower end of the upright post. The partition fits with two of the trunking parts in a way of being disposed between one next to the upper end of the upright post and the other one next to the lower end of the upright post.

What is claimed is:  
     
       1. A thin flash memory card reader comprising: 
       a) a casing having an interior;  
       b) a printed circuit board connected within the interior of the casing;  
       c) at least three different types of insertion slots for at least three different types of cards, each insertion slot having a slot base connected to the printed circuit board, the types of cards being selected from a group consisting of a flash memory card, a smart media card, a multi media card, and a secure digital card; and  
       d) a universal series bus terminal having a cable connected to the circuit board, wherein the universal series bus terminal is movable between a retracted position within the casing for storage and an extended position in which the universal series bus terminal extends out of the casing for use.  
     
     
       2. The thin flash memory card reader according to  claim 1 , wherein all of the insertion slots are provided in the casing. 
     
     
       3. The thin flash memory card reader according to  claim 1 , wherein the casing has a semicircular recess adjacent to the universal series bus terminal in the retracted position. 
     
     
       4. The thin flash memory card reader according to  claim 1 , wherein the casing has a rectangular-parallelepiped shape.
